When it comes to ensuring a consistent and robust water supply in homes reliant on well water, the role of well water booster pumps cannot be understated. These silent heroes of modern plumbing quietly work to enhance water pressure, delivering a seamless flow that meets the demands of daily life. 

In this article, we embark on a journey to explore the seven best well water pressure booster pumps, uncovering those that stand out for their performance, durability, and reliability. I’ve spent weeks reviewing, ranking, and comparing these systems to help you make the best choice for your household.

Join me as I unveil the top contenders poised to transform your well water supply into a steady, strong, and dependable force.

1. Simer 3/4 HP Pressure Booster Pump: 9.3/10

  • Overall best well water booster pump
  • $549.00

The Simer 4075SS-01 3/4 HP Pressure Booster Pump is the best well pump booster on the market. Its durable construction, heavy-duty motor, and automatic pressure-control mechanism have made it quite popular among consumers.


The Simer 4075SS-01 3/4 HP Pressure Booster Pump has a 3/4 (0.75) hp (horsepower) motor, providing sufficient power for boosting water pressure. This heavy-duty motor can handle continuous operation without overheating. 

The pump can deliver a maximum additional pressure of up to 40 PSI (pounds per square inch) and a maximum flow rate of up to 24 gallons per minute (gpm). 

The pump’s stainless steel construction ensures durability and corrosion resistance, which make it suitable for both outdoor and indoor use. In addition, it’s equipped with an automatic pressure controller that allows for easy operation and maintains consistent water pressure. The pressure controller ensures that the pump starts and stops automatically based on the water demand.

This unit is also very easy to set up because it comes preassembled and ready to install. The manufacturer has included a six-foot power cord for easy connection to a power source. If you receive a defective product or come across any issue while using this product, you can rest assured that Simer offers a three-year limited warranty with every purchase.

The Simer well water booster pump also has very favorable customer reviews, with 205 five-star reviews (out of 270) on Amazon.


Despite the glowing reviews, there are a few cons that some customers shared with me while I was doing my research. Some users have complained about the noise level of the pump. However, other users have mentioned that the pump is relatively quiet compared to other pumps they’ve used.

There have also been complaints about leaks in the pump or the fittings, which can cause water damage and reduce the efficiency of the pump. But this has been attributed to user error and the affected users have had their pumps replaced by the manufacturer.

Another issue with this pump is the price. It’s not the cheapest pump on the market, but considering its performance and durability, the price of the Simer pump is well worth it.


The Simer well water booster pump is a quick, easy, and effective solution to your well water pressure woes. This powerful pressure booster will increase your water pressure to 40 PSI which is more than adequate for most household tasks such as cleaning or yard irrigation. 

This inline pressure booster comes with a 6-foot 115-volt PSI,power cord. The pump is delivered fully assembled and ready to use. Even better, the pump activates automatically when water pressure falls below a specific level. 

If you are grappling with trickling showers or other low pressure issues due to a low powered well pump, installing the Simer 4075SS-01 3/4 HP Pressure Booster Pump will help you get back that well deserved water flow to your faucets.

2. Aquastrong Shallow Well Pump With Pressure Tank: 8.8/10

  • Best well water booster pump with pressure tank
  • Price: $238.99

Despite being a shallow well jet pump, the Aquastrong Shallow Well Pump can double up as a pretty solid booster pump for your well water. The additional five-gallon pressure tank works to maintain a consistent water pressure by storing water and compressing air to maintain pressure.


The Aquastrong 1.6HP Shallow Well Pump is a powerful and efficient water booster pump designed for a number of residential applications, not just your well water system. It features an efficient 1.6 hp capacitor motor and a durable impeller, ensuring high performance and reliability. 

With a maximum flow rate of 22 gpm, this pump can provide a steady supply of water for irrigation, home use, gardening, and lawn maintenance. The stainless steel construction of the pump ensures durability and corrosion resistance, making it suitable for outdoor use.

Everyone knows homes with well water can suffer weak water pressure. Thankfully, the Aquastrong well pump has a powerful motor and strong suction. It can efficiently boost water pressure in well water systems, ensuring a steady and consistent water supply. The automatic water booster jet pump and pressure tank will maintain a stable, consistent water pressure.

This pump is also equipped with a temperature sensor and an automatic overload stop feature. The temperature sensor helps prevent overheating of the pump by automatically shutting it off when the temperature exceeds a certain level. The automatic overload stop feature ensures safety and protects the pump from damage due to overheating.

This Aquastrong pump comes with a two-year warranty, which provides peace of mind and ensures that the pump is covered for any defects or issues that may arise during the warranty period. 


When running my tests, the Aquastrong well pump performed quite well. However, there are a few issues that I came across that are not related to its performance. First, despite a slew of positive online ratings, there is limited information available on the manufacturer of the pump, which can make it difficult to fully assess the quality and reputation of the product. 

Other issues include a few instances of short cycling brought about by a lack of clear instructions on how to adjust the pressure settings. I’ve ranked it second on my list because, unlike the Simer pressure booster pump, this unit has a lower flow rate and warranty period. Despite this, its performance as a well water booster pump is impeccable.


With a maximum flow rate of 1320 gallons per hour (GPH) and a stainless steel construction, the Aquastrong pump is a solid, durable, and reliable device. The automatic water booster jet pump and pressure tank ensure a consistent water supply and maintain stable water pressure.

Overall, the Aquastrong 1.6HP is an excellent choice for homeowners looking to boost their water supply for various purposes. I love that you can use it as a well pump, garden pump, or basement pump.

If you’re looking for an efficient well water pump booster pump that’s half the price of the Simer pressure booster, the Aquastrong 1.6HP Shallow Well Pump With Pressure Tank is a great alternative.

In the event of a defect, the manufacturer offers a 30-day free return policy and a three-month fittings and parts replacement policy for this booster pump.


The KOLERFLO pump’s low price is reflected in its build quality. A few customers have reported issues with the fittings the pump comes with, claiming they are of poor quality or do not fit properly, which can cause leaks or reduce the efficiency of the pump.

In this section, I cover every step I took to evaluate the top seven well water booster pumps available on the market.

Step 1: A big list of all available products

To begin my research, I wanted to assemble a list of every popular booster pump on the market. This involved searching hundreds of retail and manufacturer websites to see if the pumps were driving enough sales to justify a review. To broaden the scope of my research, I also called a few water pump suppliers in the vicinity. I ended up with a list of 25 different models. 

Step 2: Online reviews

Now that I had a list of models, I needed to find out how to eliminate the less trustworthy ones. 

So, I went back to the internet, but this time around I was looking at feedback from customers on websites such as Consumer Affairs, the Better Business Bureau, Amazon, and Walmart to see how each model was faring in the market. 

Finally, I was able to cut the number of reliable brands to 15.

Step 3: Product/service analysis

For this next step, I had to ask myself some critical questions regarding well water booster pumps in order to figure out which features to seek out:

  • What is the difference between a well water pump and a well water booster pump?
  • Does a well pressure booster pump include a constant pressure system?
  • What is the standard pipe size for well booster pumps?
  • Do well booster pumps truly eliminate low pressure issues?
  • Do you need to change your household piping system to install a well booster pump?
  • What are the common accessories supplied with a well booster pump (such as a pressure gauge or pressure-reducing valve)?
  • What are the different types of well booster pumps on the market?

Step 4: Speaking with real customers

I devised a strategy for the following step, in which I would contact actual customers and collect their feedback on the well booster pumps they had purchased. This wasn’t going to be a problem for me because practically all my neighbors have private wells, and I live in a semi-rural region. 

With the help of a few friends, I conducted a survey of homes within a 20-mile radius of my residence, and I spoke with a few pump suppliers to get their thoughts on the subject. It was a costly and time-consuming procedure, but I was determined to see it through.

Step 5: Interviews with manufacturers

I was interested to know whether there has been any independent testing or third-party certifications performed on these well booster pumps. As a result, I wrote to each manufacturer and requested certification documentation for each model on my list.

Step 6: Test drives

For this next step, I needed to speak from a position of authority. This meant I had to perform my own tests.

I contacted several pump suppliers in my area and asked several pumps to be sent over for testing. Despite a few negative responses, one dealer agreed to supply all seven systems on the condition that their experts observe the testing. I had the seven units delivered to my home and tested each unit using my two wells for a month.

Step 7: Ratings

For this final phase, I needed to rate the pumps based on the following criteria:

  • Maximum pressure and flow rate
  • Customer reviews
  • Safety features
  • Warranty coverage
  • Build quality
  • Motor voltage and output power
  • Ease of installation
  • Size and weight
  • Price and affordability

After ranking each well booster pump model on a spreadsheet, I was ready to sit down and write this review.


After weeks of arduous research and testing, one standout model has proven efficiency, reliability, and performance like no other—the Simer 3/4 HP Water Pressure Booster Pump

With its robust motor, this pump effortlessly amplifies water pressure, ensuring a consistent and satisfying water flow experience for households of all sizes. Its intelligent pressure switch system expertly adjusts the pump’s operation, maintaining optimal pressure levels regardless of usage peaks, while its durable construction promises years of dependable service.

While every innovation has its nuances, the minor price considerations of this pump pale in comparison to the immense benefits it brings to a household’s well water system.
